Uff da, that's a lot of computer research but hopefully you've gotten a feel for the basics by now. Now let's focus on what type of case fans to get. Since the case will need to circulate lots of air, I suggest getting fans that have high cfm (cubic feet per minute of air pushed) ratings. I think it's probably best to get the same model intake fan as exhaust fan to try to get neutral pressure inside the case (here are couple discussions on case pressure
, more pressure stuff
, and the king of all fans if you can afford it ze über-fan
). Depending on the motherboard you get and the number of fans you want, you might need a fan controller. Make sure to look at the number of fans your motherboard will be able to control to know for sure!
Getting fan filters for the intake fans is probably a good idea too because you won't want dust to accumulate inside your case.
